　　昨天一台PC Server上的数据库又出问题同样是硬盘故障

　　这两台服务器用的都是联志的国产低端PC Server 这些服务器的质量实在是差上次一台备机的硬盘损坏然后又有一台因为电源模块的问题反复重起现在这一台服务器的硬盘再次出现问题

Nov : : wap kernel: attempt to access beyond end of deviceNov : : wap kernel: : : rw= want= limit= Nov : : wap kernel: EXT fs error (device sd( )): ext _readdir: directory # contains a hole at offset Nov : : wap kernel: attempt to access beyond end of deviceNov : : wap kernel: : : rw= want= limit= Nov : : wap kernel: EXT fs error (device sd( )): ext _readdir: directory # contains a hole at offset Nov : : wap kernel: attempt to access beyond end of deviceNov : : wap kernel: : : rw= want= limit= Nov : : wap kernel: EXT fs error (device sd( )): ext _readdir: directory # contains a hole at offset Nov : : wap kernel: attempt to access beyond end of deviceNov : : wap kernel: : : rw= want= limit= Nov : : wap kernel: EXT fs error (device sd( )): ext _readdir: directory # contains a hole at offset

　　好在数据库通过DataGuard可以切换到另外一台没有数据损失

　　现在是主库所在的服务器出现问题:

　　SQL> select dbid name PROTECTION_MODE DATABASE_ROLE SWITCHOVER_STATUS from v$database;
　　DBID NAME PROTECTION_MODE DATABASE_ROLE SWITCHOVER_STATUS BMARK MAXIMUM PERFORMANCE PRIMARY SESSIONS ACTIVE

　　备库现在一切正常:

　　SQL> select dbid name PROTECTION_MODE DATABASE_ROLE SWITCHOVER_STATUS from v$database;
　　DBID NAME PROTECTION_MODE DATABASE_ROLE SWITCHOVER_STATUS BMARK MAXIMUM PERFORMANCE PHYSICAL STANDBY SESSIONS ACTIVE

　　现在需要的是一点停机时间进行切换

　　看来以后不能再采购联志服务器了
